Abstract
The influence of laser welding technology on the welding and forming effect of SUS304 stainless steel ultra-thin plate with a thickness of 0.15mm was studied,and the welding process conditions with laser power ranging from 280W to 320W and welding speed in the range of 4m/min to 5m/min were selected,and lap laser welding experiments were carried out.The research focused on the analysis of the characteristics of weld forming under the change of these process parameters,and conducted an in-depth analysis of the microstructure and mechanical properties of the welded joints with the best forming results.Experiments show that too high laser power will lead to excessive heat accumulation,resulting in weld burn-through.On the contrary,insufficient laser power will weaken the penetration capacity and cause the weld to not be fully fused,both of which are not conducive to the improvement of the bearing capacity of the welded joint.The experimental results show that the tensile shear strength of the welded joint is optimal under the process conditions of laser power of 320W,welding speed of 5m/min and swing width of 0.5mm.In addition,the fracture of the joint under all test conditions occurred in the heat-affected region,and the tensile load of the optimally formed joint reached 1.67kN,which is equivalent to 86.5%of the tensile load of 1.93kN of the base metal,and showed the characteristics of ductile fracture.关键词
